Fresnel volume georadar attenuation-difference tomography [PDF]
Geophysical Journal International, 2005 SUMMARY Georadar attenuation-difference tomography is a useful tool for imaging temporal and spatial changes in bulk electrical conductivity due to fluid flow and other subsurface processes. The most common method of attenuation-difference tomography employs the ray approximation where waves are assumed to propagate at infinite frequency.

High-resolution geophysical surveying at the Springfield Fault, New Zealand [PDF]
, 2005 To trace the active Springfield Fault (South Island, New Zealand) and map its character at shallow depths on a terrace where it exhibits no surface expression, we recorded 3-D georadar data across an approximately rectangular 110 x 40 m survey area. In

Influence of grain size, shape and compaction on georadar waves: example of an Aeolian dune
, 2012 Many Ground Penetrating Radar (GPR) profiles acquired in dry aeolian environment have shown good reflectivity inside present-day dunes. We show that the origin of this reflectivity is related to changes in grain size distribution, packing and/or grain ...

Georadarowa ocena konstrukcji nasypów drogowych [PDF]
Acta Scientiarum Polonorum. Formatio Circumiectus, 2015 W pracy podjęto próbę zastosowania georadaru do badań nasypów drogowych dla wybranego fragmentu autostrady A4 w rejonie Łańcuta. Celem wzmocnienia słabonośnego podłoża gruntowego pod autostradą zastosowano warstwy zagęszczonego tłucznia, określanego w ...
